We’ve all seen the high-energy videos of people sprinting or jumping with maximum intensity, and it’s easy to think: "That’s not for me." But here at Welcome Gym, we’re here to debunk that myth.
As we launch Week 1: HIIT Week of our 4-week Hybrid training programme, we want to show you why High-Intensity Interval Training (HIIT) is one of the most versatile and effective ways to train, whether you’re eighteen or eighty.
What Exactly is HIIT?
HIIT is simply a way of training where you give 100% effort through quick, intense bursts of exercise, followed by short recovery periods.
The beauty of HIIT lies in its flexibility. "High intensity" doesn’t mean you have to be an Olympic athlete; it just means working hard relative to your fitness level. If you’re working hard enough that holding a conversation is difficult, you’re doing it right.
Why HIIT is for "Every Body"
The primary reason we love HIIT at Welcome Gym is that it is infinitely scalable. Here is how it adapts to you:
The "Afterburn" Advantage
One of the most exciting parts of HIIT is EPOC (Excess Post-exercise Oxygen Consumption). In simpler terms, this is the "Afterburn."
Because you’ve pushed your heart rate up in short bursts, your body has to work much harder to recover after the workout is over. This means you continue to burn calories at an elevated rate for hours after you’ve left the gym, even while you're relaxing at home.
